Industrial Power Engineering and Applications Handbook By K. C. Agrawal
By KC Agrawal. This part deals with three- and single-phase a. However, reference is made to and comparisons drawn of a d. However simple a motor is, it requires careful handling to ensure optimum performance and long years of trouble-free operation.
A small drive, failing while in operation, may bring the entire process to a halt. One can visualize the loss of production that can result.
Power plants, chemicals, fertilizers, petrochemicals, paper and cement mills all require careful selection of equipment to avoid breakdown or malfunctioning during operation. Motors and their controlgears are core components that require special attention:. It also covers aspects such as shock loading, motors for hazardous locations and open transient conditions in HT motors during a switching sequence.
The precautions also cover surge protection for HT motors. The details provided cover the smallest-influence that a particular parameter can have on a machine.
A comparison between static drives and variable-speed fluid couplings is made. The subjects covered aim at providing methods to form specifications and then design a switchgear assembly for all power distribution needs. It also provides coverage of draw-out assemblies. Establishing the fault level of a system is described including the electrodynamic and electromagnetic forces that arise. The formation of the earth and movements of tectonic plates that cause earthquakes and volcanic eruptions are described.
They are covered for their specifications, selection and application. This forms an important part of power distribution at any installation to provide a standby source of supply. This part is complementary to Part II and provides technical support to switchgear assemblies and machines fed by them for surge and overvoltage protection.
It is a very useful part for all those handling HV and EHV power systems and their surge and overvoltage protection. Reflections of travelling waves and surge transferences are also described. Since the internal causes of surge generation are a consequence of switching and type of interrupter, the part provides details of the various types of interrupters in use, their switching behaviour, current chopping and quenching of arc plasma.
It also makes a detailed comparison of the various types of interrupters available to facilitate their selection and adaptation to a more appropriate surge protection scheme. Therefore temporary overvoltages also form an important parameter in a system design and its grounding method. This topic is therefore complementary to surge protection and has been dealt in detail to make a practising engineer or engineering student more aware of the behaviour of an HT system, particularly on a ground fault.
Grounding and ground fault protection schemes are described in detail with illustrations to help an engineer to select the most appropriate grounding method and ground fault protection scheme for a machine or system.
Reactive control is an important tool for voltage regulation and for optimizing available power utilization. It can also be used for attaining better stability of the system. It has therefore become a very important technique to improve an old distribution network that is being overutilized and is ailing with recurring problems such as flickering of voltage, frequent system outages and a normally low voltage at the consumer end. The author has attempted to apply reactive control to improve power distribution networks which are overloaded and which present these problems.
In this part the author provides all relevant aspects of a reactive control and carries out an exhaustive analysis of a system for the most appropriate control. Harmonic effects and inductive interferences as well as use of filter and blocking circuits are covered. Capacitor switching currents and surges and methods of dealing with these are also described.
This part considers reactive power control with the use of shunt and series capacitors. The controls may be manual or automatic through electromagnetic or static devices. Protection of capacitors and capacitor banks as well as design, manufacturing and test requirements, installation and maintenance are also covered, the main thrust being on the application of power capacitors. Power transfer is a very important area of a power system. In this part it is dealt with in detail for both LT and HT systems and for all current ratings.
For large to very large ratings, skin and proximity effects are also discussed to arrive at a design to transfer large amounts of power, without great loss, voltage drop or voltage unbalance. Technical data and current ratings for various sizes and sections of aluminium are provided with more emphasis on aluminium as it is most commonly used. The text provides material to design, engineer, manufacture and test a bus system of any current and voltage rating. The age of electricity began with the work of Hans Christian Oersted — , who demonstrated in that a current-carrying conductor could produce a magnetic field.
This was the first time that a relationship between electricity and magnetism had been established. Faraday demonstrated that it was possible to produce an electric current by means of a magnetic field and this subsequently led to the development of electric motors, generators and transformers. In Nikola Tesla — at Columbus, Ohio, USA, invented the first induction motor which has become the basic prime mover to run the wheels of industry today.
Below, for simplicity, we first discuss a polyphase and then a single-phase motor. As noted above, electromagnetic induction takes place when a sinusoidal voltage is applied to one of two windings placed so that the flux produced by one can link the other. A polyphase winding when arranged in a circular form produces a rotating field. This is the basic principle of an electric motor, appropriately termed an induction motor.
For brevity, we are not discussing the basics here. Figures 1. The winding that is static is termed a stator and that which rotates is a rotor. The rotor power P developed by torque T at a speed N can be expressed by. The magnetic field rotates at a synchronous speed, so it should also rotate the rotor.
But this is not so in an induction motor. During start-up, the rate of cutting of flux is the maximum and so is the induced e. It diminishes with motor speed due to the reduced relative speed between the rotor and the stator flux. At a synchronous speed, there is no linkage of flux and thus no induced e. For simplicity, the stator impedance has been ignored, being too small with little error.
Corollary: The speed—torque characteristics of a motor will largely depend upon its rotor parameters such as R 2 and ss X 2. The higher the rotor resistance R 2, the higher will be the torque. From equation 1. During start-up or at high slips, the value of ss X 2 will be too high compared to R 2 and equation 1.
R 2 and ss X 2 are thus the vital parameters that are used at the design stage to accomplish the desired characteristics and performance of an induction motor. In slip ring motors, the starting torque T st can be varied up to its pull-out torque T po.
See Chapter 5. For HT motors 2. One consideration is the rotor slots that are normally not made with a double cage but with tapered or deep bars, to reduce rotor size and hence, the overall size of the machine and thus the cost. Large motors are normally switched at no-load through static drives Section 6. A low starting torque therefore should not matter in the majority of cases.
These figures are for general reference only. For actual values the reader should refer to the motor manufacturer. Motors can, however, be designed to suit a particular application. Large LT and all HT motors are generally custom built. In equation 1. This is why an induction motor ceases to run at synchronous speed. The rotor, however, adjusts its speed, N r, such that the induced e. The difference in the two speeds is known as slip, S , in r. An induction motor draws a very high current during start-up as a result of magnetic saturation Section 1.
The rapid voltage change from one peak to another 2 V m Figure A within one-half of a cycle saturates excessively the iron core of the stator and the rotor. The saturation induces a very low inductance, L , and hence a low switching impedance R being low already. The inductance of the circuit L varies with the level of saturation. The duration of start-up current thus depends upon the time the rotor will take to pick-up speed to almost its rated speed. Corollary: The case of a transformer: The situation in the case of a transformer is somewhat different.
Its primary and secondary circuits form a composite unit and behave as one winding only. Since there is no air gap between the primary and the secondary windings, the combined winding impedance is less than that of a motor on switching considering secondary open-circuited or connected on load. Consequently the switching current is a little higher, of the order of 8—12 times the rated current.
If the secondary is short circuited, the short-circuit current will be much more than this, as indicated in Table As will stabilize the voltage initial spikes, so it will diminish the level of saturation, raising the value of L. The current will also decay rapidly initially and then slowly.
The same will be true for any inductive circuit other than a motor. This is a vital relationship, which reveals that during start-up and until such speed, the reactance of the motor windings ss X R 2, the rotor current will also remain almost the same as the starting current and will fall only at near the rated speed.
Refer to the current curves in Figures 1. The initial inrush current in a squirrel cage induction motor is very high. In a slip-ring motor, however, it can be controlled to a desired level. Refer to Section 5. Note For all practical purposes the stator performance data are only a replica of rotor data for torque and current.
The performance of a motor is the performance of its rotor circuit and its design. The power transferred by the stator to the rotor, P s, also known as air gap power at synchronous speed, N s, can be expressed in kW by:.

Увидев их, Джабба сразу превратился в разъяренного быка: - Я не зря создал систему фильтров. - Сквозь строй приказал долго жить, - безучастно произнес Фонтейн. - Это уже не новость, директор. - Джабба сплюнул.
Этот враждебный мир заполняли рабочие мостки, фреоновые трубки и пропасть глубиной 136 футов, на дне которой располагались генераторы питания ТРАНСТЕКСТА… Чатрукьяну страшно не хотелось погружаться в этот мир, да и вставать на пути Стратмора было далеко не безопасно, но долг есть долг. Завтра они скажут мне спасибо, - подумал он, так и не решив, правильно ли поступает. Набрав полные легкие воздуха, Чатрукьян открыл металлический шкафчик старшего сотрудника лаборатории систем безопасности. На полке с компьютерными деталями, спрятанными за накопителем носителей информации, лежала кружка выпускника Стэнфордского университета и тестер.
Приходи поиграть. - На улице еще темно, - засмеялся. - А-ах, - сладко потянулась. - Тем более приходи. Мы успеем выспаться перед поездкой на север. Дэвид грустно вздохнул: - Потому-то я и звоню. Речь идет о нашей поездке.

Никто не должен знать о существовании кольца. Может быть, стоит побродить по Триане, кварталу развлечений, и поискать там эту рыжую девицу. Или же обойти все рестораны - вдруг этот тучный немец окажется. Но и то и другое вряд ли к чему-то приведет. В его мозгу все время прокручивались слова Стратмора: Обнаружение этого кольца - вопрос национальной безопасности.
Мидж это как-нибудь переживет, - сказал он себе, усаживаясь за свой стол и приступая к просмотру остальных отчетов. Он не собирается выдавать ключи от директорского кабинета всякий раз, когда Мидж придет в голову очередная блажь. Не успел он приняться за чтение отчета службы безопасности, как его мысли были прерваны шумом голосов из соседней комнаты. Бринкерхофф отложил бумагу и подошел к двери. В приемной было темно, свет проникал только сквозь приоткрытую дверь кабинета Мидж. Голоса не стихали.
Вид купола всегда приносил ей успокоение: он оказался маяком, посверкивающим в любой час суток. Но сегодня все было по-другому. Она поймала себя на мысли, что глаза ее смотрят в пустоту. Прижавшись лицом к стеклу, Мидж вдруг почувствовала страх - безотчетный, как в раннем детстве. За окном не было ничего, кроме беспросветного мрака. Шифровалка исчезла.
